The PG109T GSM WiFi Alarm System with 4.3-inch LCD touch panel is a complete smart security solution for a home, apartment, office, garage or small business. It combines GSM, WiFi, Tuya Smart app control, sensors, remotes and RFID tags to help you protect selected areas and react quickly to alarm events.

Three-Way Alarm Notifications – Call, SMS and App Alert

When an intrusion or another alarm event is detected, the system can notify you in three ways: by phone call, SMS message and mobile app notification. You can define up to 5 alarm phone numbers, so important information reaches you or another selected person quickly.

Remote Control and Two-Way Communication

Thanks to GSM and WiFi connectivity, you can arm, disarm and monitor the alarm status remotely from your phone. With a SIM card installed, the panel can also be used for direct phone calls, giving the system additional communication flexibility.

4.3-Inch Colour Touch LCD Display

The control panel is equipped with a clear 4.3-inch colour LCD touch display. The interface is convenient for daily operation, setting alarm modes, managing sensors and configuring the system directly from the panel.

Tuya Smart App and Multi-Language Operation

The alarm works with the Tuya Smart app for convenient mobile control. The system supports voice prompts and menu languages including English, German, Russian, French, Spanish, Italian, Polish and Portuguese, making configuration and daily use easier.

Automatic Arming and Disarming Schedule

Set automatic arming and disarming schedules to match your routine. The alarm can activate when you leave for work, disarm when you return or protect the property during selected hours without manual operation.

Tamper Protection and SOS Button

The control panel includes a tamper sensor that can trigger an alarm if someone tries to remove or tamper with the unit. The panel and remote controls also include an SOS function for quick emergency alarm activation.

Backup Battery for Power Outages

The built-in 1000mAh backup battery helps keep the alarm operating for up to several hours during a power outage, supporting continuous protection even when mains power is temporarily unavailable.

Expandable Tuya Smart Security System

The system can be expanded with up to 100 compatible wireless security components, including motion sensors, door/window sensors, sirens, gas sensors, smoke sensors, remote controls and RFID tags.

This gives you the basic components needed to start protecting selected rooms, doors, windows or entrance zones immediately after configuration.

Sensors, Remotes and Accessories

The included PIR sensor monitors movement, the door/window contact reacts when an entry point is opened, and the remote controls make everyday arming and disarming fast. Additional compatible components can be added later to extend protection to more rooms and zones.

Practical Protection for Many Locations

Use the system in an apartment, detached house, office, shop, warehouse, garage or holiday property. App notifications, GSM backup communication and local siren warning help you stay informed when the protected area requires attention.

Flexible Security for Different Buildings

The alarm set is suitable for flats, houses, garages, small offices, shops and other spaces where quick notification matters. You can build a simple starter configuration first and then add compatible wireless accessories when your needs grow.

Convenient Daily Operation

The system can be armed and disarmed with remote controls, RFID tags or the mobile app, so everyday use is simple for household members and employees. Clear status information helps you check whether the protected area is secured before leaving.

GSM Backup and App Control

GSM communication gives an additional notification path through calls or SMS messages, while WiFi and the smart app make remote monitoring more comfortable. This combination is useful when you want alerts even when you are away from the protected place.

Expandable Monitoring Setup

The control panel can work with compatible sensors, sirens and accessories, allowing you to adapt the system to doors, windows, corridors, storage rooms and other sensitive areas. It is a practical choice for gradual expansion without replacing the whole alarm.
